Effect Cooperative Learning Model Type of Group Investigation Using PhET to Cognitive Learning, Interpersonal Communication and Communication Ability Capability

Abstract

This study aims to: (1) Know the influence of cooperative learning model type of group investigation (GI) using PhET to cognitive learning outcomes, (2) Analyze improvement of psychomotor learning outcomes. Research is a quasi-experiment with two group pretest-postest design. The research population is all Students of SMA Negeri 11 class XI Medan, Indonesia. The sample of research was taken two classes from population with class random sampling technique. An experimental class is taught by a Cooperative learning model type of group investigation using PhET and a control class is taught by conventional learning. The research instrument consisted of a learning result test and an observation sheet. Learning result test is used to measure cognitive learning result, observation sheet is used to obtain data of psychomotor learning result and student interpersonal communication. The result of cognitive learning was analyzed by t test, to know the effect of learning model to the learning result, psychomotor learning result and the development of interpersonal communication was analyzed by score gain test. The research results show: (1) There is influence of Cooperative learning model type of group investigation using PhET to cognitive learning outcomes, (2) Cooperative learning model type of group investigation using PhET effectively improve psychomotor learning outcomes. Through the Cooperative learning model type of group investigation using PhET, learning atmosphere becomes more effective, group cooperation in learning encourages Students to have courage in communicating opinions, communicating and sharing information with other friends in solving learning problems. As an information material the influence of Cooperative learning model type of group investigation using PhET to cognitive learning outcomes, improving psychomotor learning outcomes and the development of interpersonal communication of Students as well as alternative information materials for the selection of learning models.

Keywords: GI type cooperative learning using PhET, learning outcomes, interpersonal communication.
